Just as the Japanese yen is the unit of Japan’s legal tender, BTC (XBT) is the unit of currency for Bitcoin. Similar to how the yen is expressed as 1 yen or 100 yen, amounts and holdings are expressed as 1 BTC or 100 BTC.
Although the unit XBT is sometimes listed alongside BTC, both XBT and BTC are used independently and have the same meaning. The smallest
unit of Bitcoin is 0.00000001 BTC, but it is also sometimes called 1 satoshi, named after the first name of Satoshi Nakamoto, who is believed to be the developer of Bitcoin.
Bitcoin, which debuted in 2009, spread rapidly across the globe. As the number of users grew and the number of miners seeking to acquire Bitcoin increased, mining competition intensified, resulting in a sharp rise in price.
To acquire Bitcoin in Japan, you need to exchange Japanese yen, but the exchange rate varies depending on the time.
Since the price of 1 BTC has become too high, making it difficult to use, auxiliary units such as 1 mBTC (equivalent to 0.001 BTC) and 1 μBTC (equivalent to 0.000001 BTC) have been created.
